In medical lab reports, this quantity often appears as "Osmo, Calc" or "Osmo (Calc)." According to the international SI unit use the following equation : Calculated osmolarity = 2 Na + Glucose + Urea (all in mmol/L) As Na+ is the major extracellular cation, the sum of osmolarity of all other anions can be assumed to be equal to natremia, hence [Na+]x2 ≈ [Na+] + [anions] WebbConsider primary water overload due to polydipsia, a low solute intake, or high beer intake (potomania) as a cause of hyponatraemia. If the osmolality is more than 100 mOsm/kg (concentrated urine), ADH is acting. Assess for causes of hyponatraemia. Urinary sodium is a measure of the concentration of sodium in a litre of urine.
